Thank You, Jeeves marks Stage West’s sixth production since 2001 of one of Mark Richard’s adaptations of P.G. Wodehouse’s amusing short stories about the world’s most unflappable manservant. It’s the first time the company has repeated a script it has tackled previously, but there are still some surprises in store.

In the Wodehouse stories, the dapper British nitwit Bertie Wooster gets himself into silly schemes that he or one of his friends has devised. His valet, Jeeves, always knows how to remedy the situation — without letting on that he’s the only one with any brains in the neighborhood.

The biggest novelty about this latest show is that it features a new actor playing Bertie, the fourth to take on the role in the Stage West series. Mark Shum has been in most of the other Jeeves shows there, but in other roles. His three predecessors have all been so good that it will be hard to fill their shoes, but Shum is such a likable and funny presence onstage it shouldn’t be a problem.

As always, Jim Covault returns as Jeeves. It’s a role he was born to play. Jerry Russell directs, with a cast that includes Lee Jamison, Brandon Burrell, Ralph Burkey and Dennis Maher.
